It is not generally simple. Just take a look at all the contortions
GCC has to do to accommodate the various argument-passing strategies.
Sometimes, arguments have to be passed in general-purpose registers,
floating-point registers or the stack, and this often depends on the
type of the argument. A simple macro is hopeless except for a few
simple cases.
If you want to build argument lists on the fly, I strongly recommend
Anthony Green's libffi, available at sources.redhat.com
